The author has been a professor in electrical engineering for more than 20 years. He teaches in technical high school to classes of senior technicians. Passionate about digital electronics and computer programming, which he practices as a hobby, he took the challenge to build a drone from scratch. This book is the synthesis of his project. "Making a flying drone by yourself is quite exciting. For their first realization, beginners usually follow the general explanations given in books or on websites dealing with this subject. However, most often in these sources of information, the approach explained to build the material part results in an assembly of elements, in the manner of a "kit". And the implementation of the software part, the intelligence of the system, is limited to configuring the specialized electronic board acquired with the other elements. I suggest you to go into much more detail. You will learn how to really build your quadcopter drone, from the chassis to the computer programming in C++ of the flight controller that you will have built yourself, including the wiring of the electronic components. This book develops, in a simple and synthetic way, the detailed steps to make your drone from scratch, giving you for each part, the necessary information to understand what you achieve. The knowledge acquired will enable you to customize and improve the project according to your desires, and to undertake new ones". Olivier CHAU-HUU Main topics covered : - structure of a quadricopter and flight dynamics - stabilization principle by PID control - choice of electrical and electronic components - frame construction and wiring - programming of the flight controller in Arduino language
